This invention relates to improvements in shaker conveyers and more particularly relates to a new and improved means for laterally moving the pick-up end of a shaker conveyer.

The principal object of my invention is to provide an efficient and simplified form of selfcontained means of a novel construction, which is selectively operable to guide the pick-up end of a shaker conveyer to move in a lateral direction about a vertical swivel during movement of said pick-up end of said shaker conveyer along the ground in substantially the direction of its longitudinal axis.

This and other objects of my invention will appear from time to time as the following specication proceeds and with reference to the accompanying drawings wherein:

Figure l is a plan View of the inby end o-f a shaker conveyer trough line showing a device constructed in accordance with my invention embodied in the pick-up end thereof;

Figure 2 is an enlarged view in side elevation of the inby end of a shaker conveyer trough line, with certain parts of the pick-up member or shovel on the end thereof broken away, and certain other parts shown in substantially longitudinal section in order to illustrate certain details of my invention;

Figure 3 is a plan view drawn to substantially the same scale as Figure l, with certain parts of the shovel broken away and certain other parts shown in horizontal section in order to show certain other details of my invention which are not shown in Figure 2;

Figure 4 is a transverse sectional View taken substantially along line @-Ii f Figure 3; and

Figure 5 is a transverse sectional view taken substantially along line 5-5 of Figure 3.

In the embodiment of my invention illustrated in the drawings, a shaker conveyer trough line indicated generally by reference character ID is shown in Figure l. Said trough line is reciprocably driven at its outb-y end from a shaker conveyer drive mechanism (not shown) in a manner well known to those skilled in the art, for moving material from the inby to the outby end thereof by the reciprocable motion of said trough line. Said trough line includes a swivel trough II having a reciprocating trough I2 pivotally connected to its forward end for lateral movement along the ground about the axis of said swivel. Said swivel trough is soarranged as to permit the continuous flow of material along said reciprocating and swivel troughs to the outby end of the trough line when the forward end of said reciprocating trough is in various positions of lateral displacement with respect to the trough line.

A pick-up member or shovel I4 forms a forward continuation of the forward end of an extensible trough I5, which extensible trough is mounted for extensible or retractible movement with respect to said reciprocating trough. Said extensible trough I5 is mounted on a ground engaging shoe I6 adjacent its rear end on legs I "I, Il' extending along opposite sides of said reciprocating trough and supporting the rear end of said extensible trough in discharge relation with respect to said reciprocating trough as it is extensibly or retractibly moved therealong. The forward end of said extensible trough is supported on the shovel I4 resting on the ground.

A friction grip feeding mechanism I8 mounted on the yforward end of the reciprocating trough I2 and extending in advance thereof, is adapted to be moved into engagement with said extensible trough during alternate strokes of theconveyer, for extensibly or retractibly moving said eXtensible trough with respect to said reciprocating trough in a manner well known to those skilled in the art. Said feeding mechanism is herein shown as being of a form similar to that illustrated in the Sloane Patent No. 2,318,808, dated May 11, 1943, so need not herein be shown or described, in detail.

Referring now to the means for guiding the shovel I4 and extensible trough I 5 to move laterally about the axis of the swivel I I, during movement of said shovel and extensible trough along the ground in a direction extending generally longitudinally thereof, a ground engaging shoe I9 is mounted on the underside of said shovel for pivotal movement with respect thereto, about an upright axis, on a boss 2Q, herein shown as depending from and as being formed integrally with the bottom of said sho-vel. Said shoe is rela tively wide, to provide a wide bearing area and to form a wide support for said shovel on the ground, and is pro-vided with a plurality of longitudinally extending ribs or runners 2 I, 2I slidable along the ground, to guide said shoe and shovel for movement along the ground. The forward end of said shoe is formed on an arc struck from the center of the boss 29 and is in the form of a lip 22 spaced upwardly'- from the ground and. has slidable engagement with an arcuate groove opening towards said shoe and formed integrally with the underside of the forward portion of the shovel I.

The shoe I9 is also provided with an arcuate lip 23 spaced upwardly from the bottom thereof and rearwardly of the boss 28, which extends in a rearward direction and is struck on an arc, the center of which is coaxial with the center of said boss. Said lip abuts the underside of the shovel I4 and is abutted at its underside by an arcuate retaining segment 24 detachably secured to the bottom of said shovel.

An arm extends rearwardly from the pivotal axis of the shoe I3 and is herein shown as being formed integrally therewith. Said arm has a slot 26 at its rear end, which is engaged by a pin 21 mounted on its ends in parallel spaced ears 29, 29 projecting forwardly from the wall of a cylinder 30. Said cylinder is mounted on a piston rod 3| having a piston 32 thereon, and is slidably movable along said piston rod. Said cylinder has a rearwardly projecting guide 33 ,extending parallel to the axis thereof, which is slidably guided in a gibbed guide 34 formed in a rear wall 35 of said shovel, and extending forwardly therefrom.

Opposite ends of the piston rod 3| are shouldered and one end thereof is mounted in a side wall 36 depending from the bottom of the shovel I4 and forming a right angle continuation of the rear wall 35. The opposite end of said piston rod is mounted in an end wall 31 detachably secured to the end of the rear wall 35 opposite from the wall 3B. The shoulders of said shouldered ends of said piston rod abut the insides of Said walls and the ends of said piston rod have fittings 38, 38 threaded thereon. Said piston rod is drilled from opposite ends thereof to positions adjacent opposite sides of said piston, and the drilled portions of said piston rod open to opposite sides of said piston, so fluid may be admitted through said piston rod to either end of said cylinder, to move said cylinder along said piston rod and thus move the shoe i9 about the axis of the boss 20 in an obvious manner.

A suitable fluid pump and storage tank (not shown) may be provided to supply fluid under pressure to the cylinder 30 and suitable valves (not shown) may be provided to control the admission of uid under pressure to either end of said cylinder, to pivotally move the shoe ISabout the axis of the boss 20 in one direction or another, depending upon the direction it is desired to move the shovel.

When it is desired to swing the shovel'laterally in one direction about the swivel trough fluid under pressure may be admitted to one end of the cylinder 30 to pivot the shoe i9 so the ribs 2|, 2| extend in the angular direction it is desired to swing. During extensible movement of the eX- tensible trough l5, the ribs or runners 2|, 2| being at an angle to the longitudinal center line of said trough will guide said trough in the direction of said runners to move said trough and the reciprocating trough l2 laterally during the extension or retraction of said extensible trough,

The extensible trough l may also be swung laterally by admitting fluid under pressure to one end of the cylinder' 33 during the forward strokes of the conveyer to position said shoe in one angular position with respect to the longitudinal center line of said trough during the forward strokes of the conveyer, and by admitting fluid under pressure to the opposite end of said cylinder during the return strokes of the oon- Veyer, to move rsaid shoe to an opposite angular position during the return strokes of the conveyer.

release of fluid under pressure to opposite ends of said cylinder may be operated by hand or may be operated by the action of the conveyer in any well known manner, if desired.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the various parts may be altered without departing from the spirit and scope thereof.
